Katy Perry And 7 Other Celebs Who Have Crashed Prom

Katy Perry

Over the weekend a bunch of excited Aussie teenagers got a surprise visit from pop songstress Katy Perry. Apparently the singer wasn't too busy kissing girls or gushing wildly about her boyfriend Russell Brand to make a pit stop at the Melbourne High School prom, where she drunkenly ran through her hit "California Gurls."

But Perry isn't the only celeb who's crashed a prom or two. After the jump, more celebs who have made someone else's prom the night of their lives.

Leolah Brown, sister to Bobby Brown and aunt to Bobbi Kristina was kicked out of her niece’s funeral yesterday after verbally lashing at Pat Houston Bobbi Kristina’s former manager as well as sister-in-law to Bobbi Kristina’s mother Whitney Houston. Phew. That was a mouthful.
